DNA structure & Replication

What are the 3 steps of DNA replication?

• 1) DNA polymerase unwinds the DNA helix

  2) Helicase proof reads the strands

  3) 3 Helices are made

• 1) Helicase unwinds & unzips the DNA helix

  2) DNA polymerase adds on free floating nucleotides

  3) DNA polymerase proof reads the molecule

• 1) Unzipperase unwinds and unzips the DNA double helix

  2) Ligase proof reads the double helix

  3) DNA polymerase adds of free floating nucleotides
